The evaluation of models for UC extent (A–F) and severity (G–R). (A–C) present model for distinguishing E2 from E1. (D–F) present model for distinguishing E3 from E1. (G–I) present model for predicting Mayo score. (J–L) present model for predicting TWS. (M–O) present model for predicting MES. (P–R) present model for predicting DUBLIN score. (A,D,G,J,M,P) ROC curves. (B,E,H,K,N,Q) Calibration curves. Smoothed lines fit to the curve and vertical bar illustrates the distribution of predictions. (C,F,I,L,O,R) Decision curves. Red and blue lines represent internal and external validation. Abbreviation: AUROC, area under the receiver operating characteristic.
